This invention relates to a draw cord anchorage," and more particularly,to an anchorage for the ends of draw cords of open-mesh bags.

. Among the several objects of the invention may benoted the provisionof an improved, more secure anchorage for the ends of a draw cord in 4Claims. (Cl. 150-11) an open-mesh bag to prevent the draw cord from 7Fig. 1 is a view of a completed bag embodying the improved draw cordanchorage of the invention; and,

Fig. 2 is an enlarged fragmentary view of the bag of Fig. 1 particularlyillustrating the improved draw cord anchorage.

Fruits, vegetables and the like are often packed in open-mesh bags, suchas illustrated at l in Figs. 1 and 2, which have draw cords 3 forclosing the mouths of the bags after filling. These bags are generallyformed from lengths of openmesh fabric, such as a leno-weave fabric, cutfrom a continuous web in which the draw cord is pre-woven along onemargin. A bag is formed by folding such a length of fabric at 5 to bringthe cut ends I of the length of the fabric and the cut ends 9 of thedraw cord together, and then stitching the ends I and the bottom marginsII to form side and bottom seams l3 and I5, respectively. This resultsin an open-mouthed bag having draw cord 3 loosely interwoven thereinadjacent its mouth.

The ends 9 of the draw cord must be anchored to the bag to prevent thecord from being pulled out when it is drawn up to close the mouth of thebag. The stitching l3 cannot be relied upon for anchoring these endssince it is too coarse, due to the open-mesh characteristic of the bagfabric. Heretofore, the ends have been anchored either by knotting them,or by folding over the corner of the bag prior to stitching, or byhaving 2 the ends adhered to an adhesive splicing strip as in Geimer U.S. Patent 2,416,747. Knotting is a tedious and time-consuming procedure.The folding procedure is more satisfactory then knotting, but istime-consuming. The Geimer an chorage is available only when a splicingstrip is used in the bag seam. This invention provides an improved,secureanchorage for the ends of the draw cord which may be quickly andeasily formed without any knot-tying, folding or the like, and withoutrequiring use of a splicing strip.

As illustrated in Fig. 2, the draw cord anchorage of this inventioncomprises a staple ll driven through the bag fabric and clinched aroundthe ends of the draw cord. and a mass of adhesive l9 adhesively bondingthe ends of the cord to the bag. The adhesive is applied over asubstantial area surrounding the staple and not only bonds the ends ofthe cord to the bag but also fills or tends to fill the interstices ofthe open-mesh bag fabric, as indicated at 2|, to form a stiff matrix inwhich the staple and the ends of the cord are adhesively embedded. Thislocally stiffens the bag weave, prevents displacement of the staplerelative to the bag by preventing sliding of the staple along theindividual strands of the open-mesh bag fabric around which it isclinched, and distributes the load to increase the resistance of theanchorage topulling out of the cord. The result is an anchorage whereinthe ends of the cord are securely affixed to the bag to prevent the cordfrom being pulled out of the bag under the usual amount of force appliedto the cord in drawing it up to close the bag mouth. The staple andadhesive are applied outside of the side seam 13, so as not to obstructthe bag mouth.

Cross reference is made to our copending divisional application entitledMethod and Apparatus for Anchoring Draw Cords, Serial No. 119,914, filedOctober 6, 1949, now U. S. Patent No. 2,520,395, issued August 29, 1950.

In view of the above, it will be seen that the several objects of theinvention are achieved and other advantageous results attained.

As many changes could be made in the above construction withoutdeparting from the scope of the invention, it is intended that allmatter contained in the above description or shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitingsense.

We claim:

1. In an open-mesh fabric bag having a draw cord in the bag fabricadjacent the mouth of the bag, a staple driven through the bag fabricand clinched around the ends of the draw cord, and

tom seams, a staple driven through the bag fabric and clinched aroundthe ends of the draw cord, and a matrix of adhesive applied over asubstantial area surrounding the staple bonding the ends of the drawcord to the bag and filling the interstices of the open-mesh fabric toform an adhesive-stiffened portion of the bag in which,

the staple and the ends of the cord are embedded.

3. In a bag formed from a length of openmesh fabric having a draw cordpre-Woven therein along one margin and folded to bring the ends of thelength of fabric and the ends of the cord together, said bag havingstitched side and bottom seams, a staple driven through the bag fabricand clinched around the ends of the draw cord, and a matrix of adhesiveapplied over a substantial area surrounding the staple bonding the endsof the draw cord to the bag and filling the interstices of the open-meshfabric to form an adhesive-stiffened portion of the bag in which thestaple, the ends of the cord and a part of the side seam are embedded.

4. In a bag formed from a length of openmesh fabric having a a draw cordpre-woven therein along one margin and folded to bring the ends of thelength of fabric and the ends of the cord together, said bag havingstitched side and bottom seams, a staple driven through the bag fabricand clinched around the ends of the draw cord, and a matrix of adhesiveapplied over a substantial area surrounding the staple bonding the endsof the draw cord to the bag and filling the interstices of the open-meshfabric to form an adhesive-stiffened portion of the bag in which thestaple and the ends of the cord are embedded, said staple and adhesivebeing disposed outside of said side seam.
